              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
DisRed ion pump had to be restarted during checkout.
At 20:58 tspec free-wheeled and caused a motion error. I stopped the drives, reinitialized, and ran a few test rotations and it was fine the rest of the night. Rotation was at -177.5 when it had the motion error.
We had a fairly clear night with good seeing and, while the the humidity got a little high (80%) everything was good.
